So, let's take a look at some of the facts about Echidna in Greek mythology, through this Buzzle article. Echidna was a drakaina (a female dragon). Also called Ekhidna, her name means she-viper in Greek. She is said to be the daughter of Tartarus and Gaia, according to Apollodorus. Hesiod has a different take, and believed that she was sired by Ceto and Phorcys or Chrysaor and Callirhoe. She was half a beautiful nymph, and half a huge snake with speckled skin. She is said to have had fair skin and glancing eyes. She used to lure her victims to her cave with her captivating eyes, and then mercilessly devour them. She has been described in Hesiod's Theology as, Echidna mated with Typhon, and the pair produced some of the most ferocious giants in Greek mythology. The pair was perfect, as both were cruel evil monsters. Typhon was called the "father of all monsters." He was so huge that his head used to touch the sky, and his hands used to spread far and wide. He had hundred dragon heads instead of a human one. Arima also called couch of Typhoeus is where Echidna lived along with Typhon, and where Zeus defeated Typhon. Zeus murdered Typhon with hundred lightning bolts, but excused Echidna and her children.
